Every year hundreds of millions of malware attacks occur worldwide, and every year businesses deal with the impact of viruses, worms, keyloggers, and ransomware. Malware is a pernicious threat and the biggest driver for businesses to look for cybersecurity solutions.  Naturally, businesses want to find products that will stop malware in its tracks, and so they search for solutions to do that. But  malware protection  alone is not enough, instead what's needed is a more holistic approach. Businesses need to defend against malware entering the network, and then on top of that have systems and processes in place to restrict the damage that malware can do if it infects a user device.  This approach will not only help stop and mitigate the damage from malware, but defend against other types of threats too, such as credential theft as a result of phishing, insider threats, and supply-chain attacks.  Element 1: Malware Protection and Web Filtering The first and mo...

The threat actor behind the information-stealing malware known as  Typhon Reborn  has resurfaced with an updated version (V2) that packs in improved capabilities to evade detection and resist analysis. The new version is offered for sale on the criminal underground for $59 per month, $360 per year, or alternatively, for $540 for a lifetime subscription. "The stealer can harvest and exfiltrate sensitive information and uses the Telegram API to send stolen data to attackers," Cisco Talos researcher Edmund Brumaghin  said  in a Tuesday report. Typhon was  first documented  by Cyble in August 2022, detailing its myriad features, including hijacking clipboard content, capturing screenshots, logging keystrokes, and stealing data from crypto wallet, messaging, FTP, VPN, browser, and gaming apps. Based on another stealer malware called  Prynt Stealer , Typhon is also capable of delivering the XMRig cryptocurrency miner. In November 2022, Palo Alto Network...

Clouded vision CTI systems are confronted with some major issues ranging from the size of the collection networks to their diversity, which ultimately influence the degree of confidence they can put on their signals. Are they fresh enough and sufficiently reliable to avoid any false positives or any poisoning? Do I risk acting on outdated data? This difference is major since a piece of information is just a decision helper, whereas a piece of actionable information can directly be weaponized against an aggressor. If raw data are the hayfields, information is the haystacks, and needles are the actionable signal. To illustrate the collection networks' size & variety point, without naming anyone in particular, let's imagine a large CDN provider. Your role is to deliver, on a massive scale, content over HTTP(s). This attracts a lot of "attention" and signals, but only on the HTTP layer. Also, any smart attacker will probably avoid probing your IP ranges (which are ...

If you invite guest users into your Entra ID tenant, you may be opening yourself up to a surprising risk.  A gap in access control in Microsoft Entra's subscription handling is allowing guest users to create and transfer subscriptions into the tenant they are invited into, while maintaining full ownership of them.  All the guest user needs are the permissions to create subscriptions in their home tenant, and an invitation as a guest user into an external tenant. Once inside, the guest user can create subscriptions in their home tenant, transfer them into the external tenant, and retain full ownership rights. This stealthy privilege escalation tactic allows a guest user to gain a privileged foothold in an environment where they should only have limited access. Many organizations treat guest accounts as low-risk based on their temporary, limited access, but this behavior, which works as designed, opens the door to known attack paths and lateral movement within the resource t...

Cybersecurity researchers have taken the wraps off a previously undocumented ransomware strain called  Rorschach  that's both sophisticated and fast. "What makes Rorschach stand out from other ransomware strains is its high level of customization and its technically unique features that have not been seen before in ransomware," Check Point Research  said  in a new report. "In fact, Rorschach is one of the  fastest ransomware strains  ever observed, in terms of the speed of its encryption." The cybersecurity firm said it observed the ransomware deployed against an unnamed U.S.-based company, adding it found no branding or overlaps that connect it to any previously known ransomware actors. However, further analysis of Rorschach's source code reveals similarities to  Babuk ransomware , which suffered a leak in September 2021, and  LockBit 2.0 . On top of that, the ransom notes sent out to the victims appear to be inspired by that of  Yanluow...

Chromium-based web browsers are the target of a new malware called Rilide that masquerades itself as a seemingly legitimate extension to harvest sensitive data and siphon cryptocurrency. "Rilide malware is disguised as a legitimate Google Drive extension and enables threat actors to carry out a broad spectrum of malicious activities, including monitoring browsing history, taking screenshots, and injecting malicious scripts to withdraw funds from various cryptocurrency exchanges," Trustwave SpiderLabs Research said in a report shared with The Hacker News. What's more, the stealer malware can display forged dialogs to deceive users into entering a two-factor authentication code to withdraw digital assets. Trustwave said it identified two different campaigns involving  Ekipa RAT  and  Aurora Stealer  that led to the installation of the malicious browser extension. While Ekipa RAT is distributed via booby-trapped Microsoft Publisher files, rogue Google Ads act a...

The threat actor known as  Arid Viper  has been observed using refreshed variants of its malware toolkit in its attacks targeting Palestinian entities since September 2022. Symantec, which is tracking the group under its insect-themed moniker Mantis,  said  the adversary is "going to great lengths to maintain a persistent presence on targeted networks." Also known by the names  APT-C-23 and Desert Falcon , the hacking group has been linked to attacks aimed at Palestine and the Middle East at least since 2014. Mantis has used an arsenal of homemade malware tools such as  ViperRat ,  FrozenCell  (aka VolatileVenom), and  Micropsia  to execute and conceal its campaigns across Windows, Android, and iOS platforms. The threat actors are believed to be native Arabic speakers and based in Palestine, Egypt, and Turkey, according to a  report  published by Kaspersky in February 2015. Prior public reporting has also  tied the g...

Collaboration sits at the essence of SaaS applications. The word, or some form of it, appears in the top two headlines on Google Workspace's homepage. It can be found six times on Microsoft 365's homepage, three times on Box, and once on Workday. Visit nearly any SaaS site, and odds are 'collaboration' will appear as part of the app's key selling point.  By sitting on the cloud, content within the applications is immediately shareable, making it easier than ever to work with others.  However, that shareability is a two-sided coin. On the flip side are often sensitive links sitting on public-facing websites that can be easily accessed. The exposure caused by leaked documents can cause tremendous harm, from competitors trying to gather corporate secrets to whistleblowers sharing internal information with reporters or legislators. As integral as collaboration is to SaaS, sharing links creates a high-risk situation, and real-life breaches, that can be mitigated through the righ...

Microsoft has announced plans to automatically block embedded files with "dangerous extensions" in OneNote following reports that the note-taking service is being  increasingly abused  for malware delivery. Up until now, users were shown a dialog warning them that opening such attachments could harm their computer and data, but it was possible to dismiss the prompt and open the files. That's going to change going forward. Microsoft said it intends to prevent users from directly opening an embedded file with a dangerous extension and display the message: "Your administrator has blocked your ability to open this file type in OneNote." The update is expected to start rolling out with Version 2304 later this month and only impacts OneNote for Microsoft 365 on devices running Windows. It does not affect other platforms, including macOS, Android, and iOS, as well as OneNote versions available on the web and for Windows 10. "By default, OneNote blocks the sa...

The adversary behind the  supply chain attack targeting 3CX  deployed a second-stage implant specifically singling out a small number of cryptocurrency companies. Russian cybersecurity firm Kaspersky, which has been  internally tracking  the versatile backdoor under the name  Gopuram  since 2020, said it observed an increase in the number of infections in March 2023 coinciding with the 3CX breach. Gopuram's primary function is to connect to a command-and-control (C2) server and await further instructions that allow the attackers to interact with the victim's file system, create processes, and launch as many as eight in-memory modules. The backdoor's links to North Korea stem from the fact that it "co-existed on victim machines with  AppleJeus , a backdoor attributed to the Korean-speaking threat actor Lazarus," detailing an attack on an unnamed crypto firm located in Southeast Asia in 2020. The targeting of cryptocurrency companies is another tell...
